2007-11-21Blackfin arch: cplb and map header file cleanupMike Frysinger6-20/+19
- remove duplicated defines for the BF561 - generalize L2 support (so that it works for BF54x) and mark it executable - add support for reading/executing the Boot ROM sections (since it has data/functions we may need at runtime) - and fixup names for each map Signed-off-by: Mike Frysinger <michael.frysinger@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>

2007-11-21Blackfin arch: add support for working around anomaly 05000312Mike Frysinger1-24/+42
Anomaly 05000312 - Errors When SSYNC, CSYNC, or Loads to LT, LB and LC Registers Are Interrupted: DESCRIPTION: When instruction cache is enabled, erroneous behavior may occur when any of the following instructions are interrupted: . CSYNC • SSYNC • LCx = • LTx = (only when LCx is non-zero) • LBx = (only when LCx is non-zero) When this problem occurs, a variety of incorrect things could happen, including an illegal instruction exception. Additional errors could show up as an exception, a hardware error, or an instruction that is valid but different than the one that was expected. WORKAROUND: Place a cli before all SSYNC, CSYNC, "LCx =", "LTx =", and "LBx =" instructions to disable interrupts, and place an sti after each of these instructions to re-enable interrupts. When these instructions are executed in code that is already non-interruptible, the problem will not occur.

2007-11-17Blackfin arch: Add assembly function insl_16Michael Hennerich1-0/+1
/* * CPUs often take a performance hit when accessing unaligned memory * locations. The actual performance hit varies, it can be small if the * hardware handles it or large if we have to take an exception and fix * it * in software. * * Since an ethernet header is 14 bytes network drivers often end up * with * the IP header at an unaligned offset. The IP header can be aligned by * shifting the start of the packet by 2 bytes. Drivers should do this * with: * * skb_reserve(NET_IP_ALIGN); * * The downside to this alignment of the IP header is that the DMA is * now * unaligned. On some architectures the cost of an unaligned DMA is high * and this cost outweighs the gains made by aligning the IP header. * * Since this trade off varies between architectures, we allow * NET_IP_ALIGN * to be overridden. */ This new function insl_16 allows to read form 32-bit IO and writes to 16-bit aligned memory. This is useful in above described scenario - In particular with the AXIS AX88180 Gigabit Ethernet MAC. Once the device is in 32-bit mode, reads from the RX FIFO always decrements 4bytes. While on the other side the destination address in SDRAM is always 16-bit aligned. If we use skb_reserve(0) the receive buffer is 32-bit aligned but later we hit a unaligned exception in the IP code.

2007-11-17x86: fix reboot with no keyboard attachedTruxton Fulton1-1/+1
Attempt to fix http://bugzilla.kernel.org/show_bug.cgi?id=8378 Hiroto Shibuya wrote to tell me that he has a VIA EPIA-EK10000 which suffers from the reboot problem when no keyboard is attached. My first patch works for him: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=59f4e7d572980a521b7bdba74ab71b21f5995538 But the latest patch does not work for him : http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=8b93789808756bcc1e5c90c99f1b1ef52f839a51 We found that it was necessary to also set the "disable keyboard" flag in the command byte, as the first patch was doing. The second patch tries to minimally modify the command byte, but it is not enough. Please consider this simple one-line patch to help people with low end VIA motherboards reboot when no keyboard is attached. Hiroto Shibuya has verified that this works for him (as I no longer have an afflicted machine). Additional discussion: Note that original patch from Truxton DOES disable keyboard and this has been in main tree since 2.6.14, thus it must have quite a bit of air time already. http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.14.y.git;a=commit;h=59f4e7d572980a521b7bdba74ab71b21f5995538 Note that he only mention "System flag" in the description and comment, but in the code, "disable keyboard" flag is set. outb(0x14, 0x60); /* set "System flag" */ In 2.6.23, he made a change to read the current byte and then mask the flags, but along this change, he only set the "System flag" and dropped the setting of "disable keyboard" flag. http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.23.y.git;a=commit;h=8b93789808756bcc1e5c90c99f1b1ef52f839a51 outb(cmd | 0x04, 0x60); /* set "System flag" */ So my request is to restore the setting of disable keyboard flag which has been there since 2.6.14 but disappeared in 2.6.23.

2007-11-15[MIPS] Fix shadow register support.Ralf Baechle1-0/+1
Shadow register support would not possibly have worked on multicore systems. The support code for it was also depending not on MIPS R2 but VSMP or SMTC kernels even though it makes perfect sense with UP kernels. SR sets are a scarce resource and the expected usage pattern is that users actually hardcode the register set numbers in their code. So fix the allocator by ditching it.

2007-11-15[MIPS] Change get_cycles to always return 0.Ralf Baechle1-1/+1
This avoids us executing an mfc0 c0_count instruction on processors which don't have but also on certain R4000 and R4400 versions where reading from the count register just in the very moment when its value equals c0_compare will result in the timer interrupt getting lost.

2007-11-15[INET]: Fix potential kfree on vmalloc-ed area of request_sock_queuePavel Emelyanov1-17/+1
The request_sock_queue's listen_opt is either vmalloc-ed or kmalloc-ed depending on the number of table entries. Thus it is expected to be handled properly on free, which is done in the reqsk_queue_destroy(). However the error path in inet_csk_listen_start() calls the lite version of reqsk_queue_destroy, called __reqsk_queue_destroy, which calls the kfree unconditionally. Fix this and move the __reqsk_queue_destroy into a .c file as it looks too big to be inline. As David also noticed, this is an error recovery path only, so no locking is required and the lopt is known to be not NULL. reqsk_queue_yank_listen_sk is also now only used in net/core/request_sock.c so we should move it there too.

With 64KB blocksize, a directory entry can have size 64KB which does not fit into 16 bits we have for entry lenght. So we store 0xffff instead and convert value when read from / written to disk. The patch also converts some places to use ext3_next_entry() when we are changing them anyway.

2007-11-14pidns: Place under CONFIG_EXPERIMENTALEric W. Biederman1-0/+23
This is my trivial patch to swat innumerable little bugs with a single blow. After some intensive review (my apologies for not having gotten to this sooner) what we have looks like a good base to build on with the current pid namespace code but it is not complete, and it is still much to simple to find issues where the kernel does the wrong thing outside of the initial pid namespace. Until the dust settles and we are certain we have the ABI and the implementation is as correct as humanly possible let's keep process ID namespaces behind CONFIG_EXPERIMENTAL. Allowing us the option of fixing any ABI or other bugs we find as long as they are minor. Allowing users of the kernel to avoid those bugs simply by ensuring their kernel does not have support for multiple pid namespaces.

2007-11-14rtc: fall back to requesting only the ports we actually useBjorn Helgaas1-0/+3
Firmware like PNPBIOS or ACPI can report the address space consumed by the RTC. The actual space consumed may be less than the size (RTC_IO_EXTENT) assumed by the RTC driver. The PNP core doesn't request resources yet, but I'd like to make it do so. If/when it does, the RTC_IO_EXTENT request may fail, which prevents the RTC driver from loading. Since we only use the RTC index and data registers at RTC_PORT(0) and RTC_PORT(1), we can fall back to requesting just enough space for those. If the PNP core requests resources, this results in typical I/O port usage like this: 0070-0073 : 00:06 <-- PNP device 00:06 responds to 70-73 0070-0071 : rtc <-- RTC driver uses only 70-71 instead of the current: 0070-0077 : rtc <-- RTC_IO_EXTENT == 8 Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: Alessandro Zummo <a.zummo@towertech.it> Cc: David Brownell <david-b@pacbell.net> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-11-14I/OAT: Add support for version 2 of ioatdma deviceShannon Nelson1-0/+1
Add support for version 2 of the ioatdma device. This device handles the descriptor chain and DCA services slightly differently: - Instead of moving the dma descriptors between a busy and an idle chain, this new version uses a single circular chain so that we don't have rewrite the next_descriptor pointers as we add new requests, and the device doesn't need to re-read the last descriptor. - The new device has the DCA tags defined internally instead of needing them defined statically.

2007-11-14revert "Task Control Groups: example CPU accounting subsystem"Andrew Morton2-20/+0
Revert 62d0df64065e7c135d0002f069444fbdfc64768f. This was originally intended as a simple initial example of how to create a control groups subsystem; it wasn't intended for mainline, but I didn't make this clear enough to Andrew. The CFS cgroup subsystem now has better functionality for the per-cgroup usage accounting (based directly on CFS stats) than the "usage" status file in this patch, and the "load" status file is rather simplistic - although having a per-cgroup load average report would be a useful feature, I don't believe this patch actually provides it. If it gets into the final 2.6.24 we'd probably have to support this interface for ever.
